CMA establishes an integrated Atmospheric

observation network ， space-base, airborne-

base and ground-base observing

CMA Integrated Observing System


• Can we see the observation

instruments and data from another

perspective?

CMA new efforts on observing network improvement


A New Generation Doppler Network

How do we know the whole network is working in consensus in near real-time?

Performance parameters?Operational Status?Any alarm occurring?Data quality?parts usage and associated cost, funding needs?Instruments Life cycle ?Site environment changing?Who we service?>>>>>>

4、 Site Database subsystem

The basis of the other subsystems Based upon Sites’ ID information, equipment information

and contact information, it can offer Radar Coverage, AWS

average deployment density, tracking support ability , etc. Sites’ Database Management provides a scientific Baseline

for the network layout and construction.

Conclusion: ASOM does____

Enhances Data Quality

Improves equipment/instrument/sensor performance

Saves funding

Decreases workload and reduces staff resources requirement

knowledge repository and “lessons-learned” experiences

Identifies new requirements

Management enhancement

Help forecasters to identify data issues to correct now castings in

near real-time


ASOM Project is on going

Data QC Algorithms Development is a eternal topic

More Products to serve the public

More data comparison to support research

The evaluation results make modifications on

instruments upgrade and algorithms refining


Recommendations to WMO

Monitoring parameters should be put into the CIMO Guide

Based on monitoring requirements to guide the instruments’ design

or upgrade

Monitoring products for now casting
